Description

Technical Field

[0001] This utility model relates to the field of jewelry box technology, and in particular to a locking mechanism for an anti-loosening jewelry box. Background Technology

[0002] The jewelry box is made of high-quality materials and has a reasonable internal divider design, which keeps the jewelry neatly arranged and prevents it from getting messy or scratched.

[0003] A search revealed Chinese patent CN223068115U, which discloses a jewelry box comprising a box body, a lid mounted on top of the box body, and a hinge connecting the box body and the lid. The box body has an internal storage space containing a sponge and a lifting structure. A locking space is formed on the surface of the box body, with a first sliding groove within the locking space housing a locking mechanism. A second sliding groove is formed on the surface of the lid above the locking mechanism. This patent allows the jewelry inside the box to be lifted by a lifting plate in the lifting structure when the lid is opened, resulting in a better display of the jewelry. It also features a simple structure, low cost, and ease of implementation. The use of flexible materials protects the jewelry from scratches, and the sliding plate and recessed blocks in the locking mechanism provide efficient protection when the jewelry box is closed.

[0004] In the aforementioned existing technical solution, a sliding block is driven by a pusher block to slide within the second slide groove, causing the sliding block to engage inside the lid, thereby achieving closure between the lid and the box body. However, in actual use, during the transport of the jewelry box, additional vibrations may cause the sliding block to move within the second slide groove, loosening it from the inside of the lid, thus causing the lid to open and resulting in leakage of the contents. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes an anti-loosening jewelry box locking mechanism. The locking strip rotates around the rotating rod towards one side of the locking strip, so that the hook-shaped end of the locking strip wraps around the locking strip. The locking strip thus hooks the locking strip and fixes the position of the top cover. The elasticity of the reset spring pushes the locking strip, so that the locking strip and the side wall of the locking strip are tightly fitted, ensuring the locking strip's restraining effect on the locking strip and preventing the locking strip from loosening due to vibration.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a lock mechanism for an anti-loosening jewelry box, including a top cover, a bottom box at the bottom of the top cover, a connecting hinge fixedly installed on the side wall of the bottom box, the connecting hinge being fixedly installed on a side wall adjacent to the top cover, and a snap-fit ​​assembly provided between the top cover and the bottom box, the snap-fit ​​assembly including: A snap-fit ​​block is fixedly installed on the bottom wall of the top cover, and a snap-fit ​​strip is fixedly installed on the side wall of the snap-fit ​​block; A snap-fit ​​groove is formed on the top wall of the bottom box, and the snap-fit ​​groove is aligned with the snap-fit ​​block. A rotating rod is rotatably installed on the side wall of the bottom box, and a snap-fit ​​strip is fixedly installed on the side wall of the rotating rod. The snap-fit ​​strip is located inside the snap-fit ​​groove, the top of the snap-fit ​​strip is hook-shaped, and the inner side wall of the snap-fit ​​strip is aligned with the snap-fit ​​strip. A reset spring is fixedly installed on the inner wall of the snap-fit ​​groove, and the end of the reset spring away from the inner wall of the snap-fit ​​groove is fixedly installed on the side wall of the snap-fit ​​strip. The reset spring is arc-shaped.

[0007] In some embodiments, the top wall of the snap-fit ​​strip is provided with a guide groove, the side wall of the guide groove is inclined, and the guide groove is aligned with the bottom end of the side wall of the snap-fit ​​strip.

[0008] In some embodiments, a limiting block is fixedly installed on the inner bottom wall of the snap-fit ​​groove. The limiting block is located inside the snap-fit ​​groove at one end away from the reset spring strip, and the side wall of the limiting block is in contact with the bottom end of the side wall of the snap-fit ​​strip.

[0009] In some embodiments, a support spring plate is fixedly installed on the top wall of the limiting block. The support spring plate is arc-shaped and contacts the bottom end of the side wall of the snap-fit ​​strip.

[0010] In some embodiments, the top wall of the bottom box has two receiving slots, and a connecting retractable rod is slidably installed inside each of the two receiving slots. The top end of the connecting retractable rod is rotatably installed on the bottom wall of the top cover.

[0011] In some embodiments, a turntable is fixedly mounted on the side wall of the rotating rod away from the latching strip.

[0012] Compared with the prior art, the significant advantages of this utility model are: Firstly, this utility model, by rotating the top cover around the connecting hinge, allows the snap-fit ​​block to enter the snap-fit ​​groove, while the snap-fit ​​strip aligns with the inner wall of the latching strip. By rotating the latching strip around the rotating rod away from the hook-shaped side of the latching strip, space is created for the snap-fit ​​strip to slide downwards. After the top cover and bottom box are tightly fitted, the latching strip is rotated around the rotating rod towards the snap-fit ​​strip, so that the hook-shaped end of the latching strip wraps around the snap-fit ​​strip. The latching strip thus hooks the snap-fit ​​strip, fixing the position of the top cover. The elasticity of the reset spring pushes the latching strip, making the snap-fit ​​strip and the side wall of the snap-fit ​​strip fit tightly together, ensuring the locking effect of the latching strip on the snap-fit ​​strip and preventing the latching strip from loosening due to vibration. This solves the problem of existing snap-fit ​​components being prone to loosening.

[0013] Secondly, this utility model uses an inclined guide groove. When the side wall of the snap-fit ​​strip is attached to the side wall of the guide groove, the snap-fit ​​strip can push the buckle strip to rotate around the rotating rod to the side away from the snap-fit ​​strip. Through the automatic rotation of the buckle strip, there is no need for the operator to drive the buckle strip to rotate through the rotating rod. Attached Figure Description

[0017] This utility model provides an improved anti-loosening jewelry box locking mechanism. The technical solution of this utility model is as follows: like Figures 1-4 As shown, an anti-loosening jewelry box locking mechanism includes a top cover 1, a bottom box 2 at the bottom of the top cover 1, a connecting hinge 3 fixedly installed on the side wall of the bottom box 2, the connecting hinge 3 fixedly installed on the side wall of the top cover 1, and a snap-fit ​​assembly between the top cover 1 and the bottom box 2, the snap-fit ​​assembly including a snap-fit ​​block 4, a snap-fit ​​groove 6 and a reset spring 11; The snap-fit ​​block 4 is fixedly installed on the bottom wall of the top cover 1, and the snap-fit ​​strip 5 is fixedly installed on the side wall of the snap-fit ​​block 4; A snap-fit ​​groove 6 is formed on the top wall of the bottom box 2, and the snap-fit ​​groove 6 is aligned with the snap-fit ​​block 4. A rotating rod 7 is rotatably installed on the side wall of the bottom box 2, and a snap-fit ​​strip 8 is fixedly installed on the side wall of the rotating rod 7. The snap-fit ​​strip 8 is located inside the snap-fit ​​groove 6, and the top of the snap-fit ​​strip 8 is hook-shaped. The inner side wall of the snap-fit ​​strip 8 is aligned with the snap-fit ​​strip 5. A turntable 10 is fixedly installed on the side wall of the rotating rod 7 away from the snap-fit ​​strip 8. The turntable 10 facilitates the rotation of the rotating rod 7. The reset spring 11 is fixedly installed on the inner wall of the snap-fit ​​groove 6, and the end of the reset spring 11 away from the inner wall of the snap-fit ​​groove 6 is fixedly installed on the side wall of the snap-fit ​​strip 8. The reset spring 11 is arc-shaped. By rotating the top cover 1 around the connecting hinge 3, the snap-fit ​​block 4 enters the interior of the snap-fit ​​groove 6, and the snap-fit ​​strip 5 is aligned with the inner wall of the snap-fit ​​strip 8. By rotating the snap-fit ​​strip 8 around the rotating rod 7 away from the hook-shaped side of the snap-fit ​​strip 8, space is made for the snap-fit ​​strip 5 to slide downward. After the top cover 1 and the bottom box 2 are tightly fitted together, the latching strip 8 is rotated around the rotating rod 7 toward one side of the latching strip 5, so that the hook-shaped end of the latching strip 8 wraps around the latching strip 5. The latching strip 8 thus hooks the latching strip 5 and fixes the position of the top cover 1. The elasticity of the reset spring 11 pushes the latching strip 8 so that the latching strip 8 and the side wall of the latching strip 5 are tightly fitted together, ensuring the restraining effect of the latching strip 8 on the latching strip 5 and preventing the latching strip 8 from loosening from the latching strip 5 due to vibration.

[0018] like Figures 3-4 As shown, in this embodiment, a guide groove 9 is provided on the top wall of the snap-fit ​​strip 8. The side wall of the guide groove 9 is inclined and aligned with the bottom end of the side wall of the snap-fit ​​strip 5. When the side wall of the snap-fit ​​strip 5 is attached to the side wall of the guide groove 9 through the inclined guide groove 9, the snap-fit ​​strip 5 can push the snap-fit ​​strip 8 to rotate around the rotating rod 7 to the side away from the snap-fit ​​strip 5. Through the automatic rotation of the snap-fit ​​strip 8, there is no need for the operator to drive the snap-fit ​​strip 8 to rotate through the rotating rod 7.

[0019] like Figures 3-4 As shown, in this embodiment, a limiting block 12 is fixedly installed on the inner bottom wall of the snap-fit ​​groove 6. The limiting block 12 is located inside the snap-fit ​​groove 6 at one end away from the reset spring strip 11. The side wall of the limiting block 12 is in contact with the bottom end of the side wall of the snap-fit ​​strip 8. The position of the snap-fit ​​strip 8 is limited by the limiting block 12, which restricts the rotation range of the snap-fit ​​strip 8 and prevents the snap-fit ​​strip 8 from rotating too much around the rotating rod 7, which would cause the snap-fit ​​strip 5 to be unable to rotate around the rotating rod 7 away from the limiting block 12 along the side wall of the guide groove 9.

[0020] like Figures 3-4As shown, in this embodiment, a support spring plate 13 is fixedly installed on the top wall of the limiting block 12. The support spring plate 13 is arc-shaped and contacts the bottom end of the side wall of the snap-fit ​​strip 5. By contacting the support spring plate 13 with the side wall of the snap-fit ​​strip 5, the snap-fit ​​strip 5 is pushed upward, ensuring that the top end of the snap-fit ​​strip 8 can firmly hook the snap-fit ​​strip 5, further preventing the snap-fit ​​strip 8 and the snap-fit ​​strip 5 from coming loose.

[0021] like Figure 2 As shown, in this embodiment, two receiving slots 14 are provided on the top wall of the bottom box 2. A connecting retractable rod 15 is slidably installed inside each of the two receiving slots 14. The top end of the connecting retractable rod 15 is rotatably installed on the bottom wall of the top cover 1. Through the cooperation of the receiving slots 14 and the connecting retractable rod 15, the top cover 1 and the bottom box 2 are movably connected, making it easier to lift the top cover 1 so that the items inside the bottom box 2 can be better displayed.

[0022] The specific working method is as follows: By rotating the top cover 1 around the connecting hinge 3, the snap-fit ​​block 4 enters the interior of the snap-fit ​​groove 6, and the snap-fit ​​strip 5 is aligned with the inner wall of the snap-fit ​​strip 8. By rotating the snap-fit ​​strip 8 around the rotating rod 7 away from the hook-shaped side of the snap-fit ​​strip 8, space is made for the snap-fit ​​strip 5 to slide downward. After the top cover 1 and the bottom box 2 are tightly fitted, the snap-fit ​​strip 8 is rotated around the rotating rod 7 towards the side of the snap-fit ​​strip 5, so that the hook-shaped end of the snap-fit ​​strip 8 wraps around the snap-fit ​​strip 5. The snap-fit ​​strip 8 thus hooks the snap-fit ​​strip 5, fixing the position of the top cover 1. The elasticity of the reset spring 11 pushes the snap-fit ​​strip 8, so that the snap-fit ​​strip 8 and the side wall of the snap-fit ​​strip 5 are tightly fitted, ensuring the restraining effect of the snap-fit ​​strip 8 on the snap-fit ​​strip 5 and preventing the snap-fit ​​strip 8 from loosening due to vibration.
